They rent DR-Z400S and a few more street-oriented bikes. I think the guy I met said that they were located in Nevada City, CA, which is 27 miles north of Auburn. I don't know why their web site doesn't list their location.
Kona, Hawaii. Renting KLR650, V-Strom, DR-650, DR-Z400.
Lahaina, Maui, Hawaii. You can get a V-Strom. Interesingly, their main web site classified bikes as Harley, Scooters, and Motorcycles.
This one, on Maui, looks like a (very expensive) motorcycle tour. But they have KTM and KLR650 bikes.
It would help if the initial list noted the city as well as the state. I realize that it doesn't matter in states like Maryland or Rhode Island, but the rental place could easily be 500 miles away from where I am in California.
